Are We Alone in The Universe?

Do aliens actually exist? Mankind has asked this question since we first stared up into the night sky wondering if there is anyone else out there, somewhere amongst the billions of stars, or if we are really alone in this vast universe.

Do aliens actually exist? Mankind has asked this question since we first stared up into the night sky wondering if there is anyone else out there, somewhere amongst the billions of stars, or if we are really alone in this vast universe.

I believe that there are, in fact, extraterrestrials out there. I don’t know if they visit Earth or not, but I believe that they are out there. The universe is a pretty big place, and if life was able to evolve here on Earth, I see no reason why it couldn’t also evolve somewhere else. 

Some scientists claim that Earth is unique, and that it is the only planet that could support life like ours. That could be true, but life would evolve specifically to the conditions present on whatever planet it was evolving on. The life on another planet might not be able to survive on Earth, and vice versa, but it would be specialized to it’s own environment where it evolved. Think about it, even our own planet’s climate has changed over the course of it’s history, and life has adapted accordingly to survive and thrive in whatever ecosystem it is presented with.

There is also most likely at least a few other planets with atmospheres and environments similar to our own somewhere in the universe. There is no reason why another planet couldn’t have formed similarly to our own Earth. Perhaps there is no other planet like it at the present time, but some time in the universe’s history (or future) I am sure that there has been (or will be) another planet very similar to our own. 

Extraterrestrials may or may not have the technology to find us and our planet. Some of them are probably much like ourselves. They too probably look into the sky and wonder if they are alone. Some may be less technologically advanced than ourselves. Some probably have technology far greater than we can even imagine at this point. Others may have already driven themselves to extinction with their technology and over consumption of their resources, much like we will inevitably do. But don’t lose hope, as there are probably others who have not even evolved to intelligent, sentient beings yet, and others who have not even begun their journey of life and evolution

Some theorists believe that the building blocks for life (amino acids) or the first single-celled organisms arrived on Earth from space via an asteroid. If this is true (and it most likely is – they had to come from somewhere!), then there must have been life somewhere else in the universe. Maybe life on Earth is all that remains of a long forgotten living planet. Perhaps we are only one of many planets now inhabited by the evolutionary products of the same simple life forms. Maybe someday creatures evolved from Earth life will exist somewhere else in the universe.

It is extremely arrogant for us to think that our planet is the only one capable of supporting life in the entire universe. We are only one tiny planet revolving around one insignificant star in a vast sea of trillions upon trillions of stars. How can we possibly think that we are unique or special?

    This makes a lot of since, it is stupid to say we are the only ones in the universe. Not everyone has to live off our living conditions and we cant leave the solar system so that’s another reason.There could be one living plant per galaxy for all we know, and even then there would be a lot of life planets

    i totally agree with this, i don’t believe that we are the only ones in our universe or galaxy for that matter.

    I agree with this. Scientists have always said that life needs water in order to survive, and that we’re the only planet with liquid water.
    Yes, but what if other beings DON’T need water to survive? Just because life as we know it needs water, that’s the point- “life as WE know it.”

    Scientists who believe we are alone in the universe, who feel there are no other Earth like planets possible, and who discount the possibility of alien life are not actually scientists. In order to be a true scientist you must live by the creed that nothing is impossible. That is how discoveries are made, by believing that they can be. Great Article, glad you wrote it.

    We are utterly unique, of course there must be intelligent life out there, but like us using machines? I doubt it, even with our pathetic means of space travel, we could still colonise the entire galaxy in 50,000 years if we knew how to keep people in suspended animation for vast periods, and if as many say there are other races out there similiar to us, well they’ve had 5 billion plus years to develop and expand, they would have reached every corner of our galaxy by now…


    Lol and don’t say they’re already visiting us, ‘cus they aint, if they were why do they only abduct weirdos and nut jobs? lol.

    If we’re lucky and I mean REALLY lucky, we might one day find some ruins or something (if we don’t over-populate and ruin our planet in the mean time of course… erm ah too late for that).

    im just wondering if NASA is hiding something to all of us..we dont know,heres what i think that they have been hiding; Maybe they have send ppl already in other planets cuz of a secret hi-tech they secretly built. we dont know. uhmm, AND maybe they are other ppl that lives on other planet BUT their humans too. we dont know cuz theirs lots and lots and lots of Planets! those stars their so many! and maybe theres 2 earth in space.we dont kno cuz space is HUGE..well thats about it. i just wnat to share wut i know. by the way thank you for the free comment on your website. I really want to learn more about Astronomy and Space. I hope in the future, We will know all about space,cuz i have tons of questions. I HOPE..ty 17/02/2010
